Re: resource usage?

Hi Bob,

The 'reply' button wasn't working in IE for some reason, had to switch to FireFox.

Anyway, thanks for the answer, yes - I was able to get to the filter edit windows.

New question: after compiling how do you determine how much of the DSP available resources are used/available? The data displayed in the 'resources' window doesn't seem to change as I change the project. It might be that changing filter parameters doesn't effect resource usage.

Hi tonyc.

The resource window only works for certain SigmaDSP chips. If your project uses the ADAU170x, the way to find resource usage is:

Link-compile-download the project (with or without hardware)

Look in your project's folder for the folder called, IC1_project-name

Inside that folder there's another folder named net_list_out

Open the text file "compiler_output" in there, it will show the resources:

################## Summary ########################

Number of instructions used (out of a possible 1024 ) = 78

Data RAM used (out of a possible 2048 ) = 29

Parameter RAM used (out of a possible 1024 ) = 7

Best regards,

Bob

Thanks Bob, that makes it easy. Now I can capture my algorithm and see which part has enough resources and get the appropriate EVM. Many more questions between here and there I'm sure.

I'm amazed at how few resources are used for this example project (Binary_IndexSelectableFilter) !

FYI: the reply button is still now working in IE10, I think it's the 64-bit version.

Typo above 'now' => 'not'

Hi tonyc,

I just remembered that EngineerZone simply doesn't work with IE10,
